I believe companies usually claim back 'stolen' domains with trademark claims. I wonder if the his claim that it's "Michel in Guides" will do anything to hold this claim at bay.
Not always, and not quickly. See http://nissan.com/ for an example that's been dragging on for around 10 years or so. He's not squatting on nissan.com per se, but in my opinion is fairly close to it. It's a David vs. Goliath situation that's for sure, I'm amazed he's managed to keep the domain.
Just because a 'big' company missed out - its not his fault.
